Classic Modules Today: B4 The Lost City

In 1982, TSR published the module named "The Lost City" with the module code "B4". It was written by Tom Moldvay and illustrated by Jim Holloway. This 32-page booklet had an outer folder containing maps. In addition to an extensive dungeon complex, the module provided guidance on expanding and creating additional levels and encounters for the adventure. In 2004, for the 30th anniversary of the Dungeons & Dragons game, Dungeon magazine ranked this module the 28th greatest adventure of all time.

This "B4 The Lost City" conversion guide allows DMs to run the original module with 5th Edition rules. Also included in this guide is a handy two-page reference sheet for encounters and factions along with monster and magic item conversions, all on one two-sided sheet.

To use this conversion guide you will need a copy of "B4 The Lost City", originally available in hard-copy and now for sale in Digital format at DMsGuild.com.

This product also contains the OpenOffice/LibreOffice source files used to create the PDF. Visit Classicmodulestoday.com for instructions on creating your own classic module conversions and selling them on the DMs Guild.

I have some additional suggestions and can send them to you, if you like. May not happen until after the holidays though.

Wouldn't it make sense to use the rules for Green Slime and Yellow Mold on DMG 105 instead of treating them as Gray Ooze and Violet Fungus?

Hi Terrance! Thanks for the catch. We've updated the document to include conversion for the Baboon stats.

I also wish you would have included the map numbers on the trap listings, like they did in the original. For example, you list the Crossbow Trap (p. 5), however the original has 5 different trap situations described. As a DM, I'm already shuffling back and forth during play, without having to read the entire page to figure out which one is the Crossbow Trap. In the original it is 1a, which corresponds to the map placement.

I really liked this conversion!
It was well done and short and easy to use alongside the original module.
It was very printer friendly while providing everything I needed to run this in 5E.
Please make more of these! While I did not pay money fo [...]

I am a big fan of D&D 5e but I'm also a fan of the classic D&D/AD&D modules from the past. This is a fantastic product idea that helps make running old school modules under 5e a breeze. The presentation and content is top-notch, and in [...]

This is a great idea for a product, and as it turns out, it's a great product as well. This isn't an attempt to reinvent the wheel. The assumption is that you will get or already have the original classic version of the adventure. What this book [...]

These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.

Original electronic format

These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
